"It seemed fitting to introduce four new dishes to the existing ‘Under 500’ section in January, especially when people look to start the year with a fresh, healthier outlook," said senior brand development manager for Slug and Lettuce Nicola Stuart.

"That said, the ‘Under 500’ dishes on the current menu have been extremely popular since they were introduced back in April 2013, no matter what the season or weather. It’s about creating a menu that has a range of options to suit our customers."
